Performance increase of ultrasound liquid sprayers

摘要

The paper disolved to a problem of creation of ultrasonic resonance systems for realization of ultrasonic sputtering method in a thin layer. The physical model of such a spray method is considered in detail and the possibilities of increasing the productivity of such sprayers are shown while maintaining the high quality of the resulting aerosol. The method of calculating the geometric sizes of the acoustic resonant system of an ultrasonic spray with a tubular vibrator is proposed. The results of the simulation and experimental research of the ultrasonic sprayer, which confirm the accuracy of the proposed method for engineering calculations, are presented. The way of further possible increase of productivity of the ultrasonic spray with a tubular vibrator excited on the basic radial vibration mode is shown.
